[Bullet] Generic6DOFJoint node error

[addmix]

Godot version:
3.2.3 stable

OS/device including version:
Windows 10 64-bit

Issue description:
Setting either Node A or Node B throws the warning "set_param: The parameter 2 is deprecated."

Steps to reproduce:
create Generic6DOFJoint and assign either of the two nodes

@addmix Please upload a minimal reproduction project to make this easier to troubleshoot.

[lupoDharkael]

it happens every time so we don't need a reproduction project.
The cause is this line:

godot/scene/3d/physics_joint_3d.cpp

Line 911 in 7879b0a

PhysicsServer3D::get_singleton()->generic_6dof_joint_set_param(j, Vector3::AXIS_X, PhysicsServer3D::G6DOFJointAxisParam(i), params_x[i]);

when params_x[i] equals 2.

The warning is emited here:

godot/modules/bullet/generic_6dof_joint_bullet.cpp

Line 229 in 7879b0a

WARN_DEPRECATED_MSG("The parameter " + itos(p_param) + " is deprecated.");

I'm not familiar with this code but if you tell me how to handle this I can make a PR to solve the warning.

This is still present in 3.5.1 and I'm getting it with a PinJoint as well, not just 6DOFJoint.
